Abstract:

A 25.5 acre farm pond was stocked on a per acre basis in 1960 with 100 largemouth bass, 200 channel catfish, 471 bluegill, 212 redear, and 1,000 fathead minnow fingerlings. In the first season of growth in the pond the catfish crowded the bluegill to the degree that the bluegill grew slowly and did not produce sufficient young to serve as forage for bass after the fathead minnow had ceased to be a major component of the fish population. As a result, the bass averaged only 10.6 inches in total length at the end of their first growing season. At the same time, the bluegill were only 6.0 inches long.A flood occurred on February 24 and 25, 1961, causing a large exodus of fish. Approximately 30 pounds of bass and 70 pounds of catfish per acre left pond S-6 during the flood. With only an estimated seven bass remaining per acre, the fish population went into an overcrowded bluegill condition with most of the bluegill in the 3-inch group. The removal of 74 pounds per acre by fishing in the period June 19 through July 4, 1961, increased the severity of the crowding. After fishing had essentially ceased, the fish population tended to move towards balance. At draining, an overcrowded bluegill population was present. The pounds per acre of all fish recovered was 200. The F/C ratio considering only bass as C-species was 15.9. The catfish had not been effective predators and the number of bass was too low to correct the overcrowded condition.
